Have you seen stats for unemployment rates correlating with educational level? It runs about 14% unemployment for those without High School Diploma, 9.7% for High School, 4.5% for college degree, and even better for advanced or professional degrees. Pretty much, some college is better than no college, graduating from college is even better, and so on. The differences are pretty stark. A PhD overall (though not in Humanities) yields about a 2.5 unemployment rate. And all this is in a bad economy. Incomes for people who are employed also improve, on average, with educational attainment. It is people in my profession, then, who hold the key to employment and success generally. As a graduate professor, I train people who in turn will train others. The social scorn for people in my profession is something difficult to understand. People want their children to get into good colleges and universities, yet somehow the college professor can be a figure of deep distrust.
